Safety Maps is an ingenious service by Do projects that allows you to create a map of a safe place to meet in case of an emergency or disaster. Your map can be shared via email and printed in various sizes, and you can view maps that other users have made.
There can be very little worse than being separated from those you care about most at a time of disaster. Energy you may literally need to survive will be consumed by the gnawing anxiety you will no doubt feel for them. What’s worse, coordinating via the conventional channels may be out of the question at such a moment: phone, text, and email networks may all be down.
